Is there a reason the tokenizer can't ignore newlines and indentation/deindentation between with/etc. and the trailing colon? This would solve the problem in general, without ambiguous syntax.
At the expense of making the tokenizer context dependent?
It's already context-dependent in some sense, but this wouldn't make it any moreso. For example, the tokenizer already ignores indents/dedents when inside parens/braces/brackets, and handling this only slightly more complex than that. In particular, the trailing colon is the one not inside braces or brackets. Also, I'd avoid the term "context-dependent". It sounds too similar to "context-sensitive" ! Anyway, it looks like this isn't how the tokenizer treats braces/brackets (it ignores indent/dedent, but not newlines (I guess the grammar handles those)). What I meant to suggest was, treat "with ... :" similarly to how the OP suggests treating "with (...) :". -- Devin
